Toronto Auto Show: Mercedes-Benz

The SLR McLaren has always been fast, expensive and exclusive. Now, a topless version of the SLR raises the bar even higher. The Roadster shares the same powertrain as the coupe, a hand-built 5.4-liter supercharged V8 that generates 617 horsepower and 575 lb-ft of torque, mated to a 5-speed automatic with manual mode.
